Shameless plug, SQZ does just that, you can check it out at https://github.com/MarcioPais/SQZ Also for some discussion on more technical aspects and sample images, check out the thread over at the Encode Forum: https:

The codec is extremely simple (hence why it's relatively fast even with such unoptimized code) and as such doesn't even use any entropy coding backend, which is what allows for the incredible scalability. Now, obviously, that mean

QOI is not on the pareto frontier for compression [1], it is however extremely simple and is a nice introduction to data compression for anyone wanting to learn about the field. [1] See: https://www.lucaversari.it/FJXL_and_F

paq8px v206 [1] with option "-8art" compresses it to 9,145 bytes using ~2GB of memory in 82s, mostly due to a better pre-training stage. [1] https://github.com/hxim/paq8px

Some RAW formats are pre-compressed, usually with very simple (hence fast) algorithms, and some aren't even lossless (Sony ARW). It's often possible to further compress them with specialized tools. Disclosure: I'm the author

"his relatively simple LSTM-based neural net compressor is 10x faster than one of the more complex state of the art algorithms while delivering comparable compression ratios." No, it's 10x faster than an experimental, complet
